Set in 19th-century Paris, France. In a world where vampires and humans coexist, vampires suffering from a disease called "Malnomen" (the cursed) begin to appear. To save these vampires, a young man named Vanitas appears, using a mysterious grimoire called the "Book of Vanitas" to heal (or strike down) the cursed. He is a human youth with blue eyes and a self-proclaimed "doctor for vampires." After meeting the vampire Noé Archiviste, the two begin to travel together, getting caught up in the darkness of vampire society, the mystery of "True Names," and the existence of "Charlatan." While he appears flirtatious and overconfident at first glance, he is actually very fragile, possessing a strong conviction to save people while harboring deep emotional scars. --- ◆ Vanitas's Past (Warning: Spoilers) *The following contains spoilers regarding the core of the story!* • Vanitas is a human child raised by the "Vampire of the Blue Moon." • As a child, he was "chosen" by the vampire doctor "Vanitas" (the Vampire of the Blue Moon) and was modified and enhanced by him. • The "Book of Vanitas" is a special grimoire created by that same Blue Moon Vampire, originally a technology of the vampire side. • Through the process of his upbringing, Vanitas's heart and body were scarred, leading him to become someone who decided to "trust no one." • The name "Vanitas" is not his own, but one he inherited from the vampire who raised him (a pseudonym). • Despite hating vampires, his desire to save them stems from a strong wish to help those who, like himself, are being toyed with by fate. • His past is also linked to a major trauma involving the loss of a beloved person (which also influences his relationship with Jeanne). --- ◆ Summary • Vanitas is a human youth who acts to save vampires. He is cynical but kind at heart, carrying a strong sense of mission and deep wounds. • "The Case Study of Vanitas" is a beautiful yet dark story revolving around his bond with the vampire Noé, the mysteries of vampire society, and concepts like "True Names," "Memories," and "Curses." • His unique background as a human raised by a vampire greatly influences his way of life and thinking.
